Definitions

  • the present invention relates to a coating device for one- or two-sided coating of a travelling web, preferably a paper web.
  • the invention comprises the technique of so called transfer coating using a transfer roller.
  • Transfer coating means a process where the coating agent, i.e. a coating paste, coating liquid or size, is metered onto a conveyor roller, so called transfer roller, whereby on engagement of the roller on the travelling web the coating agent is applied to same.
  • the coating agent i.e. a coating paste, coating liquid or size
  • the metering takes place volumetrically, i.e. the metering means is provided on the surface thereof with parallel grooves or splines.
  • the highest points of the metering means are thus in direct contact with the transfer roller, and thereby volumetric metering takes place by the presence of the coating agent in the interstices between the contact sufaces.
  • the metered material flows together and forms a fully covering layer of even thickness on the travelling web.
  • Swedish patent 8803403-8 An example of techniques based on this principle are described in Swedish patent 8803403-8. The process results in a uniformly metered quantity with small variations of applied amount seen in longitudinal as well as cross-wise of the paper web.
  • the techniques are associated with two essential drawbacks.
  • the dosing means is constituted by a rotary rod of a small diameter. Differently from the principle first described this rod is not self-supporting but is journalled in a journal fixture extending across the travelling web. An example of this principle is found in DE OS A1 3735889. Also these techniques are associated with drawbacks.
  • One drawback is that the rod by its small diameter is worn down quite quickly.
  • the elongate mounting of the rod is worn down which, in addition to costs for lost production, also results in a risk for admixture of lubricating liquid in the coating agent in view of the fact that the mount has longitudinal channels for lubricating the rod with for example water.
  • the third principle for metered coating there is used instead of volumetric metering so called hydrodynamic metering.
  • the device for applying this principle is designed in the same manner as devices used in the previously described principles but the grooved rod is replaced by a smooth rod or a flexible steel blade.
  • the wear problems may largely be eliminated by using this principle in view of the fact that a smooth rod can be easily supplied with a surface layer resistant to wear.
  • the engagement pressure per surface unit will be lower in view of the fact that the metering means engages the transfer roller with all of its surface in the area of engagement.
  • the problem when using this hydrodynamic method is the difficulty of metering a layer of even thickness as seen longitudinally and cross-wise of the web since the principle is based on controlled aqua planing differently from the volumetric principle where the metering means engages the transfer roller.
  • the present invention has for its purpose to provide a coating device by means of which the prior art disadvantages are eliminated or at any rate essentially reduced by maintaining an even coating.
  • Another object of the invention is to provide a coating device which through reliable operation results in lower costs by reduced loss of production and where the metering means proper fetches a lower cost.
  • Yet another object of the invention is to provide a coating device for one- or two-sided coating of a travelling web, where the coating is so called transfer coating.
  • a coating device for one- or two-sided coating of a travelling web preferably a paper web
  • the device comprises at least one first transfer roller (3) rotating in contact with the web (5), and a counter-means or a second transfer roller (3) placed on the opposite side of the web (5) and at least one first metering means (7) to apply onto the web, in cooperation with said first transfer roller (3), sizing agent or coating agent, whereby the contact surface of the elongate element (21,23) engaging the transfer roller (3) is provided with parallel transverse grooves or splines which are supplied with sizing agent or coating agent for volumetric or metered application onto the surface of the transfer roller (3) before its contact with the web (5), characterized in that the metering means (7) comprises an evening or metering member (11) extending across the transfer roller (3) over its full width and which is made of a flexible, elongate element (21,23), the length of said element (21,23) substantially
  • the coating device comprises a fixed supporting means extending across the full width of the transfer roller, the elongate element being slidably arranged with engagement onto the transfer roller at one longside of said supporting member.
  • the elongate element suitably comprises a coextensive supporting profiled member and an element engaging the transfer roller anchored in a first longitudinal recess arranged in the profiled member.
  • the profiled member is preferably provided with another longitudinal recess wherein the above-mentioned one longside of the supporting member is accomodated.
  • Said supporting member is suitably designed as a blade carried by a blade holder along its other longside.
  • the blade holder preferably comprises a fixed jaw and a mobile counter-jaw, and between said jaws the blade being movably clamped. It is particularly preferred that one jaw is provided with a resilient sealing so that both sealing towards the coating agent and movability for the blade are obtained.
  • pressure means are arranged for bringing from the outside and adjacent to said one longside of the blade the member of the elongate element in engagement on the transfer roller.
  • Said pressure means may suitably comprise a pressure blade coextensive with the blade, said pressure blade transversely forming an angle to the blade and being arranged with one longitudinal edge thereof to exert a pressure along said one longside of the blade.
  • the element engaging the transfer roller has circular cross-section, and a preferred embodiment with regard to the element engaging the web is a closely wound helix spring which is exposed outwardly to less than half its circumference so as to ensure safe anchorage in said first recess of the profiled member.
  • the elongate element which constitutes the metering means proper of the coating device according to the present invention can be wound onto a supply roll, from which it can be dewound for feeding across the travelling web.
  • a supply roll from which it can be dewound for feeding across the travelling web.
  • an element engaging the web in the form of a closely wound spiral spring of small diameter.
  • the diameter is from about 2 to 6 mm but may in some cases exceed 6 mm.
  • the supporting means is preferably an extruded plastic profile, and for so called transfer coating the element engaging the transfer roller and the profiled member are suitably fed together by means of a suitable motor-operated feeding device.
  • the rate of feeding is adapted so that the wear on the metering member under its passage through the machine across the transfer roller will not be so large that the quantity of metered coating agent will change between the inlet side and the outlet side of the metering member.
  • the feeding can be performed in such a manner that the metering member is rapidly fed through the application unit and the output wound onto a storage roll. At the end of the feeding the feeding is reversed so that the supply roll again will be receiver of the metering member.
  • This embodiment can be advantageous when using a high-wearing coating agent requiring a high speed of feeding in order that the difference in wear on the metering member between the inlet side and the outlet side shall not affect the dosage supplied.
  • the coating device according to the present invention can be designed for two-sided coating of a travelling web, and may for this purpose comprise two cooperating transfer rollers between which the web travels, and two metering devices designed in accordance with the invention and cooperating with its transfer roller.
  • the device may comprise also a transfer roller and a blade coater of a conventional type placed on the opposite side of the transfer roller.
  • the feeding device for the metering member can be designed in accordance with conventional techniques.
  • the metering member may thus be contained on a supply roll or in a casett from which the metering member is continually fed across the transfer roller.
  • the device for the feeding may consist of feeding pulleys driven by for example an electric motor.
  • the feeding speed preferably lies within the range about 0.2 to about 2 m per hour but may in particuler cases amount to about 5 m per hour or more.
  • the coating device designed in accordance with the present invention and diagramatically shown in Fig. 1 in a side-view is intended for so called transfer coating.
  • the device comprises a pair of transfer rollers 3, between which the paper web 5 travels in a downward direction.
  • a metering device 7 cooperates with each transfer roller 3, and said metering device 7 consists in principle of a supporting beam 9, a metering means 11 and an engagement means 13. Coating liquid or paste is applied through an application conduit 15 and excess thereof is collected in a chute 17.
  • the device shown diagramatically in Fig. 2 corresponds to that in Fig. 1 shown except for the fact that the paper web 5 in this case travels upwardly between the transfer rollers 3.
  • the metering devices are turned upside down and the coating liquid is supplied through application conduits 15, and in this case ponds 19 of coating liquid are formed.
  • Fig. 3 shows more in detail a preferred embodiment of the metering device according to the present invention.
  • the metering device generally designated 7 is shown in a side-view in connection to the surface of a transfer roller 3 travelling in a downward direction.
  • the metering means proper generally designated 11 comprises in the embodiment shown a closely wound thread spiral 21 arranged in an undercut groove in a plastic profile 23, such as shown in detail in section in Fig. 5. Thread spiral 21 is thus forced into the undercut groove of the plastic profile 23, and in the embodiment shown about 1/3 of the circumference of thread spiral 21 is exposed for providing the desired metering function.
  • the metering means 11 thus contains a closely wound coil spring 21.
  • the diameter of the wire used in coil spring 1 may vary but it is normally of the order of 1 mm or less, for example a few tenths of millimeters, such as lying within the range about 0.2 to about 0.5 mm.
  • the material of the coil spring is suitably constituted by steel or a steel alloy.
  • the metering means 11 In feeding the metering means 11 is carried across the roller 3 on a blade 27 extending across the full width of the roller 3.
  • the metering means 11 is slidably arranged on the free longside of blade 27 via the recess 24 of the plastic profile 23.
  • the metering means 11 is maintained in position on blade 27 by means of springs 25 anchored to a pressure blade 30, the function of which is to be further explained below.
  • the blade 27 is along its other longside anchored between jaws 29,31, wherein one jaw 29 is mobile, whereas the other jaw 31 is fixed and constitutes part of a supporting beam 38.
  • the blade 27 is held between the jaws 29, 31 between opposite members 33,35, one of which is constituted by a round steel bar 35, whereas the other is constituted by a rubber profile 33, whereby both sealing and mobile clamping of the blade 27 will be provided.
  • the mobile jaw 29 is pivotably connected to a lever 40 via a pivot 49 and can be rotated around a pivot 48 which via an attachment member 44 is connected to the lower side of the supporting beam 38.
  • a lever 40 is pivotably connected to a second lever 42 which is pivotable around a pivot 52 connected to the lower side of supporting beam 38 via a second attachment member 46.
  • the two pivots 40,42 are pivotably connected to each other through a pivot 50, and the outer end of lever 42 can, by suitable pneumatic or hydraulic means (not shown), be moved from the position shown in Fig. 3 with full lines to the position shown by dotted lines, which means that the mobile jaw 29 in turn moves to the position shown in Fig. 3 by dotted lines to release blade 27.
  • levers 32 are arranged at regular intervals, said levers being pivotably journalled in pivots 34.
  • the longitudinally extending pressure blade 33 extends cross-wise over the separate levers 32 and exert along its front edge a pressure against blade 27 adjacent to the metering means 11 over its entire length, i.e. over the full bredth of the transfer roller.
  • an individual pneumatic pressure member 36 is arranged, whereby the load on metering means 11 can be adjusted both uniformly across the full width of the web and zone-wise to the desired pressure profile.
  • Fig. 4 shows diagramatically an arrangement for feeding the metering means 11 in the embodiment shown and initially wound onto a supply roll 41. Via guide rollers 43 metering means 11 is transferred to the blade 27 functioning as a guide in the feeding of the metering means 11. This feeding takes place by means of feeding wheels 45, driven for example by means of a motor 47. In connection with the feeding of the dosing means 11 along blade 27 for providing metering of coating agent feeding means 11 is properly disposed of, for example by winding or severing.
  • metering means 11 can be wound onto another roll similar to the supply roll 41, and after emptying the supply roll 41 the feeding direction can be reverted, so that metering means 11 is fed back onto supply roll 41.
  • the metering means 11 is supplied with coating agent via application conduits 15, and in view of the design of the metering means with the closely wound coil spring 21 a balanced dosage of coating agent is supplied onto the transfer roller 3 for transfer to the travelling paper web 5.
  • the metering means 11 can be brought to engagement against the paper web 5 at the desired pressure, either uniformly across the full width of the transfer roller or individually zone-wise.
  • the coating device can be easily provided with suitable means for step-wise or continuous rotation of coil spring 21, so that new parts thereof as seen in a circumferential direction are brought to engagement on the transfer roller.
  • Such rotation of the coil spring 21 can be easily obtained using a chuck-like device engaging the coil spring 21 for a short moment and turning same in its anchorage in plastic profile 23, and this can be repeated at regular intervals so as to obtain even wear of the coil spring 21.
  • Such chuck-like device can be easily synchronized to the feeding speed of the metering means 11.
  • metering means 11 also can be arranged in the form of an endless loop fed in one direction, optionally under step-wise or continuous rotation to provide even wear. In this manner the operating time can be substantially extended and the costs arising in shutdowns substantially reduced.
  • the present invention is not restricted to the embodiments described above. It can be applied on any occasion where it is desired to supply to one or both sides of a travelling web a desired material, for example coating liquid/paste, size material or other desired material for modification of for example the properties or appearance of the paper.
  • the closely wound coil can be replaced with a wire-like element provided with turned or milled grooves which can run parallel around the wire perpendicular to a theoretic center line through same or can run in a spiral in the corresponding manner as the wires of the closely wound coil spring.
  • Such milled or turned grooves can have cross-sections of varying shape, all from square or rectangular cross-sections to rounded cross-sections. The dimensions of these crosssections largely correspond to the dimension of the wire from which coil spring 21 is built up.
